50 UNESCO natural World Heritage Sites

"The pyramid-shaped, wooded mountain of Monte San Giorgio beside Lake
Lugano is regarded as the best fossil record of marine life from the
Triassic Period (245–230 million years ago). The sequence records life
in a tropical lagoon environment, sheltered and partially separated from
the open sea by an offshore reef. Diverse marine life flourished within
this lagoon, including reptiles, fish, bivalves, ammonites, echinoderms
and crustaceans. Because the lagoon was near land, the remains also
include land-based fossils of reptiles, insects and plants, resulting in
an extremely rich source of fossils." — UNESCO
